Benefits of Solar Energy

Solar energy provides numerous advantages that will enhance your home for years to come.

  • Smaller power bills: Generating some or all of your own power will cut power costs long-term.
  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can reduce or eliminate your home's dependence on fossil fuels.
  • Better energy independence: Solar systems with battery storage operate through blackouts and emergencies, and you won't have to rely on the power grid for your safety and well-being.

How To Choose the Best Solar Company in San Diego

The more informed your company research is, the better your solar system will ultimately work. Make your choice based on the following essential elements.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar photovoltaic (PV) systems, water heaters, boilers, HVAC, and pool heaters. Contractors must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. Check a company's website for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most trusted trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in San Diego

Your solar modules' model will affect how much power you can generate. Monocrystalline panels perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

You can also add electric car (EV) chargers and battery backup systems. These will increase your total project price, but they can increase your solar system's efficiency. Not every solar company offers these add-ons, so look for a contractor that installs them if it's crucial for you.

A majority of San Diego homeowners select solar systems sized for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to set up, considering both parts and installation. You can see more specific cost information in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,226
Solar Polycrystalline $956
Thin-Film $559
Solar Battery $784
Solar Home EV Charger $2,942

Financing Solar Energy in San Diego

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar loans, cash payments, solar leases and power purchase agreements (PPAs). Though it requires a large up-front payment, cash is the most affordable choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the second most effective option. As with a car or home loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to use your panels for a set monthly rate, while PPAs let you pay just for the energy you use, similar to an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We recommend working with a provider that offers multiple financing options. Talk to each representative about what's available, and obtain more than one estimate for the best odds of staying within your spending limits.

The table below lists the average payback periods for different capacities of solar systems in San Diego.

The IRS allows you to claim a 26% federal tax credit on the full cost of the solar system, so long as you purchase it before 2032. City and state governments and utilities might also offer their own rebates, incentives, and financing programs that could save you more money.

Solar System Capacity Estimated Payback period
1 kW 1.4 years
2 kW 2.7 years
5 kW 6.8 years
10 kW 13.7 years

Frequently Asked Questions About Solar in San Diego

How much energy and money could I save per year by switching to solar?

On average, San Diego homeowners shell out roughly $1,659 per year on power bills. Once you repay your solar array, you could save $1,637.07 for every kilowatt you produce.

How popular is solar energy in San Diego?

Yes, solar energy is gaining popularity in San Diego. Some homes already use solar power on-site or through utility grids, and they're backed by a state solar economy with 74255 jobs and counting.

Should I anticipate a boost in my property value after switching to solar energy?

Yes, solar panels will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a dark or rainy

Even if your property has high tree cover, you could still use solar energy. Your technician will maximize your system's performance by selecting the proper site for panels, installing a battery backup system, positioning them to capture the most sunlight throughout the year, and cleaning them regularly. This way, you can store solar power and use it as necessary.

What can I do to predict my home's solar viability?

One common way to find your home's solar viability is by using PVWatts. This free, powerful tool considers local weather and topography, tree cover, panel efficiency, and system size to determine how much energy your array could generate. However, it's not a substitute for consulting with a local solar installation company, who can create a full estimate with the most updated data.

How long does the solar panel installation process take?

Your solar job's duration will depend on its size and complexity, as well as San Diego's permit and inspection procedures. It could take a couple of weeks to a few months on average.

What's the difference between a PPA and a solar lease?

After you sign a PPA, your solar contractor will not charge to install or maintain your new panel array. Instead, you'll pay them only for the electricity you generate. Typically, PPAs last for 10–25 years or until you "buy out" of the contract.

If you choose a lease, you'll make fixed monthly payments.

With both leases and PPAs, you do not own your panels and lose eligibility for most incentives. Further, you'll have to "buy out" or transfer the contract if you sell your home during the term.
